To study animal behavior sometimes requires some subterfuge. The reason for this is simple; organisms don't wish to cooperate with biologists, especially when we want them to hold still and wait for a predator. Now you might take the Jessica Lang/King Kong approach, but biologists are not cruel, generally, and besides if you took the wings off, it doesn't send the right signal. Another approach is to make a model, and digital photography and color printing make this easier than ever. Shortly after this model was deployed by one of our students, a group of tourists were seen clicking away, so at some level, she can be pretty sure the model works, but then again, are you more observant than a bird?
